Through the system developed at the University of La Laguna is detected the patient’s hypnotic state at any time and provides the most appropriate dose of anesthesia, the academic center reported today in a statement.

Albino Juan Mendez, a researcher at the Anesthesia Control Group at the University of La Laguna, shows that with this system is individualized drug dose infused with the characteristics of each patient.

This group of researchers has developed a software tool, along with the team of anesthesiologists at the Hospital Universitario de Canarias, to facilitate the work of these health professionals.

The research has been published in the journal Computer Methods in Biomechanics and Biomedical Engineering.

Through sensors and a monitor, the system records the electroencephalogram (EEG) of patient and bispectral index (BIS), a unitless parameter that quantifies the hypnotic state and is related to the level of consciousness.

The bispectral index value between 100 (high alert as possible) and 0 (absence of cortical electrical activity, the more profound state of unconsciousness).

This research focuses on the region of bispectral index for general anesthesia, ie between 40 and 60.

The data are processed on a computer that includes specific control software and can act on the pump that injects the anesthetic to regulate their numbers.

The software is based on algorithms PID (Proportional Integral Derivative) adapter, a feedback control mechanism that automatically calculates the appropriate dosage based on measured and desired values.

To validate the technique the researchers have successfully performed simulations with various models developed by them and in addition the fifteen patients have been tested in volunteers, aged between 30 and 60, the Hospital Universitario de Canarias.

Preliminary results for both operating room and in simulation show that the system provides a satisfactory performance and applicability in the operating room with reasonable expectations of success, Albino said Mendez.

Scientists hope that the method helps to improve operational performance at the time of anesthetic dose and optimize patient recovery times and reduce the costs of interventions.

The study is a commonly used anesthetic, propofol, but could use others, such as isoflurane.

The technique also has application in the regulation of other physiological variables such as blood glucose level, temperature or blood pressure.

Alopecia areata is falling relatively quickly, the hair of various parts of our body, forming plaques or patches of alopecia, well circumscribed, usually single and round, but may be multiple and extensive, confluent or not. It can affect the scalp hair of the beard area, eyebrows, eyelashes, axilla, pubis, etc. It may even bring down the entire body hair (alopecia universalize).

This is a common reason for consulting a dermatologist, where you have to make a differential diagnosis with other diseases such as fungal infections (ringworm) or trichotillomania (hair pulling habit of continually) to avoid malpractice and, in the best, only useless.

A curious thing happens in alopecia areata is initially white hair respects people who already had white hair before the disease. However, if the disease persists, gray hair is also falling. Moreover, when the hair starts to reappear, it is initially white or lighter than normal, and then acquires its normal pigmentation.

The extent or degree of impact of alopecia areata is probably the most important prognostic factor, so that in the case of total alopecia (falling to 100% of scalp hair) or universal (100% drop of scalp and body) the possibility of complete cure is less than 10%.

Alopecia areata is associated with an increased frequency of other diseases, such as alterations in the nails (occur in up to two thirds of cases of alopecia areata), with autoimmune diseases (especially thyroid problems), atopic dermatitis (incidence is twice that in the general population) or even psychiatric or psychological disorders (such as anxiety or depression). Stress has often been cited as a cause of alopecia areata, although when controlled trials are designed, they have not always provided conclusive data. Although some studies have confirmed that stressful life events may precede episodes of alopecia areata, others have failed to demonstrate such a correlation. What seems clear is that the nervous system is closely related to our skin, and that how we react to stressful situations (in the broad sense) can influence and modulate the appearance of skin diseases, including alopecia areata. This has been demonstrated even in models of alopecia areata in mice which investigated the hypothalamic-pituitary-adrenal axis and its changes related to sustained stress.

Although there is a wide range of available treatments for alopecia areata (intralesional and topical corticosteroids, topical minoxidil, PUVA therapy, bexarotene, or any use of the best hair regrowth products …), since there are spontaneous remissions in 33% -50% of cases within one year from the start of injuries, other potential attitudes is to explain the patient’s illness and not perform any drug treatment. Psychotherapy and stress management methods can be useful in some cases.

Thus, seasonal variation, especially in cold weather, can influence bodily activity modifying sympathetic tone, blood viscosity, blood pressure and heart rate, which tend to increase, in turn raising the demand for oxygen the body.

With the drop in temperatures, those with cardiovascular history are more likely to suffer complications as cardiovascular diseases are mainly associated with cold. In this sense, in winter stands the prevalence of cardiovascular diseases such as ischemic heart disease, angina pectoris and acute myocardial infarction.

“This is mainly due to the cold causes a narrowing of the arteries of the body and can lead to coronary level, a decrease of the blood supply to the heart,” says Dr. Leandro Plaza Celemín, president of the Spanish Heart Foundation (FEC). Mortality and morbidity from heart disease (CHD) follows a heterogeneous geographical distribution among different countries and even within countries. In this sense, “Metabolic Syndrome (MS) is unevenly distributed geographically in the Spanish territory,” explains Dr. Montserrat León, Aragon Institute of Health Sciences. “Certain other areas are almost twice the frequency of the disease and also match those which have highest rates of CHD mortality,” he adds.

This is one of the conclusions drawn from research work conducted by Spanish specialists and coordinated by Dr. Leon. “This study is part of a broader conducted by the Working Group of Metabolic Syndrome Spanish Society of Cardiology, specifically, Section of Preventive Cardiology and Rehabilitation,” says this doctor.

According to investigators, the idea of raising this study came to the high prevalence represents the Metabolic Syndrome according to several American studies and the lack of epidemiological data of this disease in Spain. The group of specialists who participated in the work belong to different disciplines: family physicians, cardiologists, internists, and company doctors, residents, and statistical and other technicians.

The study sample consisted of workers recruited in the health examinations conducted by their companies.

“We use this group for the ease in obtaining the data from their annual medical examinations for the high prevalence of risk factors in this age and the impact they might have on prevention measures.

The girl, who lives in Sha Tin District, has already been discharged. He had cough, fever and runny nose. Since 1999, only Hong Kong have been detected in seven cases in humans caused by influenza virus type H9 (H corresponds to the initial one of the coat protein, hemagglutinin, of which there are 16 types). But fortunately, all were mild. Just in case, authorities have recommended to avoid, if possible, contact with poultry, which are the usual focus of these viruses.

Hong Kong is one of the world sentinels for influenza. It’s in Southeast Asia, where usually start pandemics (one of the surprises of the last H1N1 is to begin in Mexico), there is a high population density and domestic birds and has the technology to identify the variants of the pathogen.

What side effects have been reported among persons vaccinated?
Of about 100,000 health professionals vaccinated between October 21 and November 10, four adverse events “serious” were identified by Afssaps two neurological disorders, allergic reactions and respiratory disorders. It was first reported a possible case of Guillain-Barre to moderate, occurred in a woman 37 years after treatment, has recovered well and was able to return home.

The second case is angioedema, an allergic reaction that can, in some cases, cause a serious risk of suffocation. In this case, it occurred within minutes following vaccination in a 26 year old woman whose condition after treatment, improved “without any sequelae. The third case of neurological disorders (numbness of the upper limbs) seen in a man of 34 years, too, is better. Finally, a 30 year old woman with a history of allergy presented a respiratory (bronchial spasms, shortness of breath). “His condition is improving under appropriate treatment,” says Afssaps.

What is Guillain-Barre?
It is an attack of nerves that results in rapid paralysis, usually starting at the legs, then back up the body. In 85% cases, the patient recovery is complete, but 5% of people die and 10% are affected negatively. In France, there are each year between 1 700 and 1 800 cases of Guillain-Barre. The risk of developing this condition after a flu shot is one or two cases per million persons vaccinated. According to experts, in two thirds of cases, this syndrome is triggered after a viral or bacterial infection. The infectious disease stress is therefore more likely to have Guillain-Barre after the flu after vaccination.

These side effects are they related to the vaccine?
In the case of angioedema, it is quite possible. “It is an uncommon side effect, but can occur after vaccination,” says Carmen Kreft-Jais, head of pharmacovigilance Afssaps. For three other cases, she said that investigations are underway to try to decide on possible vaccine accountability. “It is quite possible that there is no link between vaccination and the onset of the cases of Guillain-Barre. But we can never be certain, “says Professor Odile Launay, head of clinical investigation center of vaccinology Cochin-Pasteur in Paris.

Last Monday, Didier Houssin, director general of health, reminding that every day, normally between three and five people were hospitalized in France for Guillain-Barre. “Inevitably, there will be other cases in the coming weeks. Among these patients, some may have been vaccinated in previous weeks. And it will be very difficult to know whether the syndrome is linked to the vaccine or has another origin, says an expert. For Afssaps, these side effects does “not undermine the risk-benefit balance” of the vaccine.

Changing lifestyle habits can reduce the risk of stroke. It is best not to wait for more than 30 years who want to prevent diseases that may have started growing in the body. Then after that age is starting to become evident excesses of youth.

They are said to people over 50 who are more prone to heart attack today but certainly people are dying younger because of this evil. Lead a sedentary lifestyle because they do not practice any sport, they do not exercise; they eat poorly, consuming liquor and snuff. In recent years it has been said that years die about 15 million people a myocardial infarction.

Walking, an activity less effort and requires only discipline, willingness and little time. With only 30 or 60 minutes of daily walking you are oxygenating your body, strengthen their heart and breathing and regulating metabolism.

Jogging or running, this type of activity or exercise requires more capacity but goes along with walking because after having a routine of constant path will be much easier and fun start to run. Running are encouraged a lot more heart and heartbeat.

Walk up and down stairs. Sometimes humans use escalator or the elevator, go in your car or motorcycle right to chair or bed and devotes little or no physical activity. Walking up stairs, lower, running and walking are simple but safe ways to reduce risk for heart attack. Establish a daily routine is paramount and can do so at their place of residence or work if necessary.

For those who prefer the cardio fitness will be the greatest help to prevent heart attack risk in this type of activity is much movement, coordination, burn calories and stimulation of cardiac and respiratory activity.

Do not exceed capacity

Excessive exercise and physical activity can also lead to a heart attack. So it is vital to be taking heart rate, blood pressure checked and be careful not to exceed one’s limits. There are people who have suffered heart attacks during sports and even died.

Sport is a source of health but must be properly controlled and if possible addressed. For walking, running up and down stairs is not up to you to monitor the limit switch and guard his heart.

There are many pluses with Fifty-One Trio E-cigarettes. The first being its attractive and professional packing. 2nd pro obviously is the reputation of the company making it. The company is known for its efficient products and its great after sale service that includes fast shipping and something that consumers only dream of, a life time warranty to replace a faulty product.

To be frank, I was not impressed with the amount of vapors I got with a first few puffs as the atomizer supplied takes some time to get primed. After a few puffs you will get as much smoke as you get from your regular cigarettes. Fifty-One Trio is far ahead of Blu and Luci in this aspect though it is still behind Fifty-One Duo in the amount of vapors produced.

Fifty-One Trio does not hit the throat as much which is a relief for many smokers. Those who are just casual smokers, do not like harsh cigarettes in any case, but those who smoke heavily (and I am certainly one of those) would find this E-cigarette is a little short on this aspect.

Fifty-One Trio tries hard to mimic the taste of a real cigarette, but does not feel quite like a real one. This is because of the difference in ingredients and also because an E-cigarette can never really taste like a real one because there is no fire involved. Good thing about this E-cigarette is the seal of approval from the doctors as they found no carcinogens in this cigarette. What this means is that even if you are not getting the real feel, you are being spared from the harmful effects of 4000+ carcinogens.

If you go out of stock, you can purchase refills from anywhere in the market. However, you have the option of pre-filled cartridges that are available in menthol and tobacco flavors. The reason for selling only 2 flavors is to discourage kids from taking up these-cigarettes. All in all, a great substitute for real cigarettes.

In every child in suspected bronchial asthma must perform baseline spirometry and bronchodilator (give the child to inhale a drug) to demonstrate that the airway obstruction is reversible (characteristic of asthma). Finally, an etiologic diagnosis, led to seek the cause that triggers the symptoms, to identify the cause is the most important step to control the disease.

In fact, in Spain, one in five children with asthma lose six or more days of school due to illness, and approximately 3% of all children aged 9 to 12 years visited the ED for an asthma attack . In addition, in recent years has increased the number of children 6 years with this disease.

As indicated by a statement, in most cases it is mild or moderate asthma, the work of pediatric primary care “is essential” for diagnosis, treatment and monitoring of the disease, as highlighted in the Congress.

In this regard, SEPEAP experts stress the importance of performing a medical history “methodical and thorough” to get an accurate diagnosis of the disease.

According to Dr. Carmen Gancedo, a pediatrician and member of the SEPEAP, “to affirm the presence of asthma in a patient, through clinical history pediatricians we must note the presence of cough, wheezing or chest tightness, among other factors” .

Pediatricians agree, noting that the main objective is to obtain and follow the evolution of the disease, and do our best for the child or adolescent has a good quality of life, with no limitations on daily activities and absence of symptoms. ALLERGIES

This conference has also highlighted that 35 percent of allergic children have ever eaten, accidentally, food excluded.

Specifically, food allergies affect between 6 and 8% of children under 10 years. In the words of Dr. Christopher Coronel, a member of the Spanish Society of Pediatric Outpatient and Primary Care (SEPEAP) and a pediatrician at the Health Center of Seville Laffón Lover, “in Spain, these allergies have a prevalence of approximately 7% and in Specifically, cow’s milk affects up to 7.5% of children during the first year of life. ”

In regard to this issue, as has been noted in the congress, the most allergenic foods are eggs, cow’s milk, fish, legumes and nuts.

Feeding

Another issue that has been treated in the National Congress of the Society of Pediatric Outpatient and Primary Care is the power, where it was stressed that 50 percent of children not eating well.

Specifically, experts stress the importance of differentiating between children who have no interest in food for the selective and those with an aversion to food, and that “often what happens is that the child does not meet expectations parents and altered, sometimes dramatically, family life, “says Dr. Venancio Martinez SEPEAP member and pediatrician at the Health Center of El Llano, Gijon.

Associated diseases

* Inflammation of the bronchial mucosa : In recent years it has been shown that treatment of inflammation is the most important part of asthma treatment. So far, put too much emphasis on bronchodilation, but if there is inflammation, the effects of bronchodilators are ephemeral. There are several medications that have anti-inflammatory effect in bronchial mucosa, but the most powerful and effective are corticosteroids (cortisone) inhaled. Inhaled corticosteroid doses used are very low and produce a topical effect without the side effects of oral administration, intravenous or intramuscular injection. Inhaled corticosteroids have become the most important drug in the treatment of asthma. They begin to be prescribed in patients with persistent asthma, ie those in which symptoms occur several days a week, and in those in which symptoms occur at night. For those symptoms occur sporadically, for example one or two times every 15 days, it is necessary to start with steroids and bronchodilators may be sufficient.
* Bronchospasm : Inhaled corticosteroids do not act immediately, even when they effect after a few days of treatment, bronchospasm forwards. But for the immediate treatment of it is used bronchodilators are usually given by inhalation. There are two basic types according to the duration of action: long-acting bronchodilators are taken morning and evening every day, whether or not the symptoms, while short acting are usually reserved to take in case of need (shortness of breath, coughing, etc). The ultimate goal is that patients resort to short-acting bronchodilators on rare occasions. Otherwise, it is necessary to promote anti-inflammatory treatment. Obviously, patients with severe asthma, despite maximum anti-inflammatory treatment, often require bronchodilators.
* Allergy : In patients who demonstrated an allergic component, treatment with antihistamines may be beneficial. On the other hand, with certain allergies are effective immunological treatments (vaccines) that can significantly help in controlling asthma. However, as effective in treating allergies is to avoid or minimize exposure to allergens. For example, in the case of allergy to dust mites, hygienic measures are simple house can significantly reduce their presence.

Associated diseases and general measures
Gastroesophageal reflux and chronic sinusitis can aggravate or cause asthma, so it is important to rule in cases of asthma do not respond to usual treatment.

Obviously, people with asthma should completely abstain from smoking because snuff smoke is an irritant that causes inflammation of the bronchi. Occupational exposures that cause asthma (flour, wood, etc..) Should be avoided if possible by proper air ventilation and use of protective masks. In severe cases it is necessary to change jobs.
